Windows 10: Can't change which app is assigned to a file type.

I'm trying to change a file type associated with an extension. When I click on the "Change" line in "File Explorer Options" all I get s a blue window with a white gear symbol instead of the file type list. What am I doing wrong?

W10's brain damaged way to assign apps <-> file types


Unfortunately, none of the methods described in the tutorial worked:

Method 1 & 7: I don't want to reset all file types! It took me already long enough to assign a couple of types that had no defaults. Furthermore, my wife hates Edge as browser, so assigning it to handle all its possible file types is no option here.

Method 2. The "Open with..."-approach does not work either. Edge is not listed here.

Method 3 & 4: There is only that dreaded "Look for an app in the store" and no "Look for another app on this PC" option in the file type dialog (although for Edge that probably wouldn't work anyway, since there is no "edge.exe" to assign here as it is a "modern app". ||-(

Method 5: There is no protocol involved here. We are dealing with local files here.

Method 6: The set defaults by app method does not work either. For some strange reason on my Surface, "epub" is one of the listed file types for Edge, but on my wife's computer "epub" is missing from fhat list. And there seems no way to edit this list of file types. :-(

Method 8: Edge is not listed as possible application. And one can not assign it using "Other app"...

I guess the root of the problem is, that Edge - at least on this system - is not listed as possible handler for epub files. Guess my next action will be to dive into the registry...

 

How to remove a default file association app from a file type in Windows 10 - set to "no default app" associated

Hi Goa,

When you selected a certain program in “Open With” there is no option to revert this change. Since DLL files are independent, there is no other program than you can replace the default program with it.
To help you out with your concerns with default programs, we'd like to ask you some questions:

• What were the recent changes made on your computer before you experienced this issue?
• What are the workarounds you have done so far?

• Have you assigned Excel as a default program for DLL files? We would like to confirm this.

You can navigate this by following the steps on this link:
Change default programs in Windows 10. Once there, click
Open Default apps. Then, click Choose default apps by file type.
Look for the DLL file, see if you can remove the assigned program in the DLL format.

Your response will be much appreciated.

 

App to open .c6e0ec and .e8d549184 files

Hi Hitkary,

It seems that there is no default app set to open these kind of files. Can you still recall the type of app or program that opens this kind of file?

For us to isolate this issue, we suggest assigning a default app or program to open it. Follow the steps below:

• Open Settings and click System.
• Click Default apps.
• At the bottom, click Choose default apps by file type.
• Scroll down and look for the .e8d549184 file.
• Once found, click the + sign on the right and select the app you want to use.

Once you've successfully set the default app, try opening the file again and let us know how it goes.

Regards.
